Oil Coolers - available from Flexolite

The cooler consists of alternating layers of oil-ways and air-ways to give the maximum surface area for efficient heat exchange. The simple, brazed construction also provides an ideal strength-to-weight ratio. The standard thickness (front to back measurement) is 50mm (2”), there are two widths readily available and a wide range of heights – normally reckoned in “rows”.

Coolers can be supplied with a variety of connections, but JIC and BSP male threads are the most widely-used (other types can be supplied to order). The coolers are reasonably robust but rubber-mounting is advised in harsh usage or where vibration is a problem. It is recommended that coolers over 16-rows high are mounted using both top and bottom plates or have a clamping arrangement between the top and bottom plates. For really rough use we recommend the CR range of coolers (see below).

Ideally, coolers should be mounted where there is a good supply of cool air - but this is not always possible and we can supply electric fans if required. We suggest that any oil cooler system incorporates a thermostat, not only to help the engine warm up but also to protect the cooler from pressure spikes when starting from cold.
